Just.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide one kind to be used for automobile air conditioner compressor
The die casting of front cover is not necessarily to secondary operation axis hole, improves the manufacture efficiency of front cover.
To achieve the above object, the utility model provides following technical solution:
A kind of die casting for automotive air conditioner compressor front cover, cover half and and cover half including offering sprue
The dynamic model of cooperation, the fixed half and moving half split form the type chamber for forming front cover, the dynamic model be located at sprue just under
Side offers the link slot of reversed sprue direction recess, and the connection to sprue direction protrusion is plugged in the link slot
Column, the connecting column are threaded through in sprue and cooperatively form the circular gate being connected to type chamber with sprue.
So set, fixed half and moving half cooperatively forms type chamber, molten metal is added in type chamber by sprue, passes through pressure
Casting is plastic front cover；Wherein, by the way that connecting column to be plugged in link slot, molten metal can be made to avoid connection post part, when
After molten metal solidification, connecting column is separated with blank, the axis hole of bearing block can be formed, without carrying out secondary operation axis hole, is mentioned
The high manufacture efficiency of front cover, reduces manufacturing cost；Meanwhile the characteristics of circular gate is that charging is uniform, is flowed everywhere on circumference
Speed is roughly equal, and melt flows state is good, and the air in type chamber is easily drained, and weld mark can avoid substantially, can uniform pack circle
Tubular finished product avoids weld bond and partial stowage from satiating and is deformed, is eccentric, improves product quality.
Further setting: the side of the cover half is equipped with the locating piece to dynamic model direction protrusion, and the side of the dynamic model is opened
Equipped with the locating slot being embedded for locating piece, the two sides of the locating piece slope inwardly towards locating slot direction, form the first guide surface.
So set, the cooperation of locating piece and locating slot positions when can mold for fixed half and moving half, dynamic model is avoided to close fixed
There is deviation in the molding of mould, and the cooperation of guide-localization block and locating slot is capable of in the design of the first guide surface, without precisely aligning.
Further setting: the locating slot is equipped with limited block, offers the limit being embedded for limited block on the locating piece
Position slot, offer molding upper half chamber on the limited block, the bottom of the limiting slot offer with molding upper half chamber cooperation at
Type lower half chamber.
So set, the cooperation of dynamic model and cover half is smart when the cooperation of limiting slot and limited block can further increase molding
Accuracy, molding upper half chamber and molding lower half chamber cooperation can be used in the protrusion part of shaped article, and since it sets up separately in dynamic model
On cover half, it is not necessarily to additional pulled core structure, mold structure is simplified, reduces costs.
Further setting: the two sides of the limited block slope inwardly towards limiting slot direction, form the second guide surface.
So set, the cooperation of guide limiting stopper and limiting slot is capable of in the design of the second guide surface, without precisely aligning i.e.
Molding can be achieved.
Further setting: first guide surface and locating slot, the second guide surface and limiting slot are enclosed gas vent.
So set, the intracavitary air of type can be discharged by gas vent when injecting molten metal, meanwhile, metal
Liquid adds thermogenetic various gases that can also be discharged by gas vent, it is possible to reduce the various defects of product.
Further setting: core pulling upper half slot is offered on the dynamic model, offers on the cover half and matches with core pulling upper half slot
The core pulling lower half slot of conjunction, the core pulling upper half slot and core pulling lower half slot are enclosed the core-pulling cavity worn for core-pulling member.
So set, the design of core-pulling cavity can be used in forming the groove that front cover is located at side, it is not necessarily to secondary operation.
Further setting: the core-pulling member is core pulling axis, and the convex block abutted for core pulling axis is provided on the cover half.
So set, the design of convex block can be positioned for core-pulling member, when core-pulling member is connected on convex block, can be used in
The shrinkage pool of front cover side is formed, secondary positioning, and the position without controlling core-pulling member is not necessarily to, facilitates the positioning of core-pulling member.
By using above-mentioned technical proposal, the utility model is compared compared with the prior art, has the advantage that the mold is logical
Cross the cooperation of dynamic model, cover half, connecting column, can straight forming axis hole, be not necessarily to secondary operation, improve the manufacture efficiency of front cover；Together
When, the circular gate cooperatively formed by connecting column and sprue, making charging, uniformly the air in type chamber is easily drained, and is improved
Product quality.
